If you want to specify the probability whether a given operator performs mutation (say) or just copies parents and returns them, the parameter you're looking for is 'likelihood'.

If you want to specify the probability of doing mutation type 1 versus mutation type 2 versus crossover or whatever, the tool you want is called ec.breed.MultiBreedingPipeline.
